Can I be blocked? Can't start a conversation w/ HotDogSandwich

have a box currently on a truck out for delivery to Ryan (@hotdogsandwich) who left our conversation thread, and when I try to start a new thread I get a pop-up saying I can't start a conversation with him anymore. I honestly wouldn't have even been paying attention if it weren't for the California fires and wanting to make sure he was at a safe location and the box could arrive on time.
